Goodwe GW30K-MT Three-Phase Inverter 30kW SMT 3 MPPT

Product Description

The Goodwe GW30K-MT 30kW SMT 3 MPPT Three-Phase Inverter is a high-performance on-grid inverter for commercial rooftops. It integrates three MPPT trackers with two strings each, supports up to 1100 V DC, and offers a maximum efficiency of 98.8%. Its IP65 design, fuse-free electronics, and extensive communications make it the balanced option between power, reliability, and control for 30 kW installations.

Main Features

• Nominal AC power: 30 kW (max. output 33 kW).
• 3 MPPT × 2 strings; MPPT range 200–950 V; max. Vdc 1100 V; start-up 180 V.
• Current per MPPT up to 25 A (I_sc max. per MPPT 31.3 A).
• Max. efficiency 98.8%; ηEU > 98.5%; THDi < 3%.
• IP65, integrated DC isolator, type III SPD, and optional AFCI.
• Wi-Fi/RS-485/PLC with SEMS portal and Modbus-RTU protocol.
• 30% DC oversizing and 10% AC overload to extend the generation window.

Advantages or Benefits

• Zone optimization: three trackers reduce losses on rooftops with different orientations or inclinations.
• Industrial reliability: solid capacitor and active ventilation for operation in warm environments with minimal derating.
• Safe operation and compliance: integrated protections and AFCI option for DC arc mitigation.
• Advanced energy management: zero export function and reactive power control with GoodWe meter.
• Reduced O&M cost: “fuse-free” design and string monitoring facilitate diagnostics.

Purpose or Applications

Self-consumption and reduction of energy charges in SMEs, public buildings, commercial premises, and small warehouses with 400 V 3-phase grid. Suitable for high-power modules (half-cut, bifacial) and scenarios with multiple PV arrays.

Technical Specifications

Compatibilities

GoodWe three-phase meter (DTSD/GM) via RS-485 for zero export and load balancing. Recommended DC boxes 3×2 with gPV 15–20 A fuses, isolators ≥ 25–32 A per MPPT, and type II SPD on DC/AC. On AC, 63 A panel (consider 80 A depending on cos φ and line length) with type A/B RCD and type II SPD.

Goodwe GW30K-MT 30kW SMT 3 MPPT Three-Phase Inverter is the professional choice for commercial projects prioritizing production, safety, and comprehensive monitoring.
